[Dale]

Hi all,
 
Any ideas of the age of this artefact, at first glance it looks Celtic, it has tooling marks all around from being made, its had a lot of contact over the years before being lost as the high points are rounded and very smooth, it sits up all tho a little wobbly the bottom is flat with what looks like a  threaded hole was this done at a later date?

Any thoughts welcome thanks
